2018 Beta 350 RR-S Dirt Bike Review Price

With a lighter weight and performance that has never been better, the 2018 Enduro RR is coming to the market with many new features. This new generation of RR models, in particular, the new 2018 Beta 350 RR-Race Edition Dirt Bike, is characterized by their ease of handling, their solidity and the high degree of reliability thanks to a significant evolution of the engine, running gear and suspension. The review and specifications of new 2018 Beta 350 RR-S Dirt Bike are given below.

2018 Beta 350 RR-S Dirt Bike – Features and Price


A series of new features common to both the two and four-stroke engines have been introduced. These developments have led not only to an increase in performance compared to the 2017 Beta 350 RR-S Dirt Bike but also about a 1.7 kg decrease in weight for both versions.

A complete overhaul of the clutch has resulted in improved scalability, precision, and increased stability at different operating temperatures. It has also made the clutch more compact and lightweight, which has been put to good use in refining the lines of the 2018 Beta 350 RR-S Dirt Bike by allowing for a greater tapering of the external clutch cover.

While it can still be ordered as an option given the engine arrangement, the great work done by the engineers in improving the reliability of the electric starter has allowed for the removal of the kick-start lever, providing significant weight reduction.

This eliminates any possible uncertainties during gear shifting by improving transmission precision. Output optimization by rigorously testing the injection mapping on the 4-stroke engine and timing advance curves on the 2-stroke engine allowed for a new filter box the be introduced.

Besides, both the 2-stroke and the 4-stroke versions have been expressly engineered for their particular architectures. Dedicated maps for each engine displacement can be applied because of the introduction of dual injectors. This improves engine performance (in particular for mid and high rpm) and boosts mileage due to increased mixture control.


Compared to older models, the new 2018 Beta 350 RR-S Dirt Bike features the completely redesigned front-end has led to a notable decrease in weight along with an increase in flexural and torsional rigidity characteristics. This improvement in the structural layout has resulted in a consistent boost in riding precision and handling.

The bike now has a leaner and more aggressive look thanks to a slimmer filter box and rear end. Higher power and reliability, coupled with lighter weight. With precise calibration to suit the demands placed on it by the new chassis, this was developed to improve sliding and increase rigidity while being lighter like in 2018 Beta 480 RR-Race Edition. It uses a mono-shock absorber which has been adapted for the 2018 frames with new settings.

A revision of the external profile and the internal layout enhances engine performance, particularly at low rpm. New skid plate (2-stroke versions only) allows for speedier removal by improving fastener accessibility.

New muffler heat shield: Improved protection for the rider on both the 2- and 4- stroke versions from burns. Takasago Excel rims come with a new opaque black finish designed explicitly for BETA. It is available in new colors and graphics.
